N2 - On the model of tench (Tinca tinca, Cyprinidae), a fish species extensively bred in European aquaculture, we tested possible selective advantage in parasite resistance in triploids over diploids. During four sampling periods 81 diploids and 79 triploids were collected from a breeding pond in Vodňany, Czech Republic. More than 12000 individuals of parasitic metazoans belonging to 13 species were recorded. Host sex did not affect either parasite abundance or parasite species richness. In concordance with our prediction, diploids tended to have higher parasite load than triploids throughout the year. Nevertheless, significantly higher overall parasite abundance in diploids compared to triploids was confirmed only in summer. Host ploidy appeared to be associated with the susceptibility or resistance to particular parasite species. Whilst diploid tench showed higher susceptibility to adult trematode Asymphylodora tincae, triploid tench was parasitized more by larval cestode Valipora camplylancristrota. The occurrence of Gyrodactylus tincae and Myxozoa spp. was only seasonally dependent. Generally no clear association between parasite infection and selected haematological, physiological and immune parameters measured were recorded.
